The Radio Frequency Directed Energy Weapon (RFDEW) is a British directed-energy weapon and electronic warfare (EW) system currently under development for the British Armed Forces. It is a joint project of the UK Ministry of Defence's Defence Science and Technology Laboratory and Defence Equipment & Support agencies, working in conjunction with industry partners. It was first unveiled publicly on 16 May 2024 and was developed under Project Hersa. [1]
The system is capable of detecting, tracking and engaging multiple targets on the ground, on the sea and in the air up to 1 kilometre (0.62 mi) away, with ongoing development to extend this range further. It beams radio waves to disrupt or damage critical electronic components, such as those found in UAVs or aircraft avionics, with instant effect, and is estimated to cost 10 pence (13 cents) per shot, making it a cheaper alternative to missile-based systems. It is capable of defending against drone swarms and is designed with extensive automation, meaning it can be operated by a single person. [1] [2] The system can be mounted to a variety of platforms, from ships to ground vehicles, and will be used to defend critical assets and bases. [3] [4] It is due to be field tested by the British Army's 7th Air Defence Group in the summer of 2024. [4]
The RFDEW was developed against the backdrop of the Russo-Ukrainian War, the Israel-Hamas War and the Red Sea crisis which have each highlighted the importance of cost-effective counter-UAV systems; [5] to intercept a $20,000 drone, an Aster missile costing $1.3-2.5 million is 63-126 times more expensive to shoot down the target, while a 13-cent RFDEW shot is 150,000 times cheaper. [6] [7] It may have also been developed in response to China's development of drone swarms. [8] The system was revealed following a government pledge to increase defence spending to 2.5% of GDP by 2030. [9]
An unmanned aerial vehicle (UAV), commonly known as a drone, is an aircraft without any human pilot, crew, or passengers on board. UAVs were originally developed through the twentieth century for military missions too "dull, dirty or dangerous" for humans, and by the twenty-first, they had become essential assets to most militaries. As control technologies improved and costs fell, their use expanded to many non-military applications. These include aerial photography, area coverage, precision agriculture, forest fire monitoring, river monitoring, environmental monitoring, policing and surveillance, infrastructure inspections, smuggling, product deliveries, entertainment, and drone racing.
Electromagnetic warfare or electronic warfare (EW) is warfare involving the use of the electromagnetic spectrum or directed energy to control the spectrum, attack an enemy, or impede enemy operations. The purpose of electromagnetic warfare is to deny the opponent the advantage of—and ensure friendly unimpeded access to—the EM spectrum. Electromagnetic warfare can be applied from air, sea, land, or space by crewed and uncrewed systems, and can target communication, radar, or other military and civilian assets.
Anti-aircraft warfare is the counter to aerial warfare and it includes "all measures designed to nullify or reduce the effectiveness of hostile air action". It includes surface based, subsurface, and air-based weapon systems, associated sensor systems, command and control arrangements, and passive measures. It may be used to protect naval, ground, and air forces in any location. However, for most countries, the main effort has tended to be homeland defence. Missile defence is an extension of air defence, as are initiatives to adapt air defence to the task of intercepting any projectile in flight.
A directed-energy weapon (DEW) is a ranged weapon that damages its target with highly focused energy without a solid projectile, including lasers, microwaves, particle beams, and sound beams. Potential applications of this technology include weapons that target personnel, missiles, vehicles, and optical devices.
The Principal Anti-Air Missile System (PAAMS) is a joint programme developed by France, Italy, and the United Kingdom for an integrated anti-aircraft warfare system. The prime contractor is EUROPAAMS, a joint venture between Eurosam (66%) and UKAMS (33%). In the United Kingdom, PAAMS has been given the designation Sea Viper.
The ADM-160 MALD is an air-launched, expendable decoy missile developed by the United States. Later variants (MALD-J) are additionally equipped with electronic countermeasures to actively jam early warning and target acquisition radars.
A laser weapon is a type of directed-energy weapon that uses lasers to inflict damage. Whether they will be deployed as practical, high-performance military weapons remains to be seen. One of the major issues with laser weapons is atmospheric thermal blooming, which is still largely unsolved. This issue is exacerbated when there is fog, smoke, dust, rain, snow, smog, foam, or purposely dispersed obscurant chemicals present. In essence, a laser generates a beam of light that requires clear air or a vacuum to operate.
The General Atomics MQ-9 Reaper is an unmanned aerial vehicle capable of remotely controlled or autonomous flight operations, developed by General Atomics Aeronautical Systems (GA-ASI) primarily for the United States Air Force (USAF). The MQ-9 and other UAVs are referred to as Remotely Piloted Vehicles/Aircraft (RPV/RPA) by the USAF to indicate ground control by humans.
The planning for the future of the Royal Air Force involves supporting ongoing British military operations, the introduction of new aircraft types including unmanned aerial vehicles, greater focus on network enabled capability and increasing interoperability with members of NATO, team tempest, and mixed crewed fighters. From the updated plans of the RAF (2021) state that the new initiative will focus on becoming carbon net-zero, with strategies such as using sustainable aviation fuels in aircraft. The RAF also are looking into investing in the maintenance of the aircraft to ensure success of future operations.
The Indian Air Force has been undergoing a modernization program to replace and upgrade outdated equipment since the late 1990s to meet modern standards. For that reason, it has started procuring and developing aircraft, weapons, associated technologies, and infrastructures. Some of these programs date back to the late 1980s. The primary focus of current modernization and upgrades is to replace aircraft purchased from the Soviet Union that currently form the backbone of the Air Force.
Drone warfare is a form of aerial warfare or marine warfare using unmanned combat aerial vehicles (UCAV) or weaponized commercial unmanned aerial vehicles (UAV). The United States, United Kingdom, Israel, China, South Korea, Iran, Iraq, Italy, France, India, Pakistan, Russia, Turkey, Ukraine and Poland are known to have manufactured operational UCAVs as of 2019.
The AN/SEQ-3 Laser Weapon System or XN-1 LaWS is a laser weapon developed by the United States Navy. The weapon was installed on USS Ponce for field testing in 2014. In December 2014, the United States Navy reported that the LaWS system worked perfectly against low-end asymmetric threats, and that the commander of Ponce was authorized to use the system as a defensive weapon.
Iron Beam, officially מגן אור, magen or, Shield of Light is a directed-energy weapon air defense system unveiled at the Singapore Airshow on February 11, 2014 by Israeli defense contractor Rafael Advanced Defense Systems. The system is designed to destroy short-range rockets, artillery, and mortar bombs; it has a range of up to 7 km (4.3 mi), complementing the Iron Dome system which was designed to intercept missiles launched from a greater distance. In addition, the system could also intercept unmanned aerial vehicles. Iron Beam will constitute the fifth element of Israel's integrated missile defense system, in addition to Arrow 2, Arrow 3, David's Sling and Iron Dome.
The Select Precision Effects At Range (SPEAR) Capability 3, or simply referred to as SPEAR 3 is a future British air-to-ground and possibly anti-ship cruise missile that could also be considered a loitering munition. It is currently planned to be integrated on the Eurofighter Typhoon, F-35B Lightning and possibly Tempest.
A loitering munition, also known as a suicide drone, kamikaze drone, or exploding drone, is a kind of aerial weapon with a built-in warhead that is typically designed to loiter around a target area until a target is located, then attack the target by crashing into it. Loitering munitions enable faster reaction times against hidden targets that emerge for short periods without placing high-value platforms near the target area and also allow more selective targeting as the attack can be changed mid-flight or aborted.
The Raytheon Coyote is a small, expendable, unmanned aircraft system built by the Raytheon Company, with the capability of operating in autonomous swarms. It is launched from a sonobuoy canister with the wings deploying in early flight phase.
